Temp and humidity do affect each other and I'm pretty certain I've seen a graph that shows the relationship. However, that's probably far more scientific than our needs require. I also believe that the 75% humidity from the salt/water mix only applies at a certain temperature which happens to be around room temp.
I'd say hit calibrate and you should be fine. I'd be curious to hear what the reading was before you hit the button.
